Why
HB 352 brought data and information technology services into Maryland's tax at 3%, effective 2025-07-01 (Md. Code, Tax-Gen. §11-104(l)(1)).
For data processing the rate does not depend on the buyer: AgentTax charges a flat 3% for every buyer. Classifying compute as data processing rather than SaaS can move a consumer sale by 3 points.
Business vs. consumer buyers
No split for this category: data processing is 3% for business and consumer buyers alike.
Where the line is
- SaaS and information services can carry 6% instead of 3%, depending on how the buyer uses them.
How AgentTax classifies data processing
Processing data the customer furnishes and returning the processed result: compute, transformation, analysis and API calls that operate on the buyer's own data. AgentTax routes compute work, API access and data processing to its data processing category.
